CVE-2023-34941
XSS in Asus Rt-N10Lx Firmware 2.0.0.39
Raw vector
CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:NCVSS and EPSS are reproduced from their sources (NVD, FIRST EPSS). Risk Priority is our own derived reading, not an NVD score.
Summary
CVE-2023-34941 is a medium-severity Cross-site Scripting (CWE-79) vulnerability in Asus Rt-N10Lx Firmware. Its CVSS base score is 5.4 (Medium).
Operationally, exploitation aligns with the MITRE ATT&CK technique Protocol or Service Impersonation (T1001.003); ranked in the top 2% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
A stored cross-site scripting vulnerability exists in the urlFilterList function of the Asus RT-N10LX Router version 2.0.0.39. The flaw, tracked as CWE-79, arises from inadequate sanitization of the URL Keyword List text field and permits injection of arbitrary scripts or HTML. The CVE applies only to this unsupported firmware release and carries a CVSS 3.1 score of 5.4.
An attacker with low privileges can supply a crafted payload to the affected field; when the stored value is later rendered, the script executes in the browser of any user who views the page, resulting in limited confidentiality and integrity impacts. The product is explicitly noted as unsupported by its maintainer, and the two reference URLs point to the same public proof-of-concept repository without additional mitigation guidance. The associated EPSS score has remained flat at 0.0569 with no material rise after disclosure.

Likely Mitigating Controls AI
Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Penetration testing submits XSS payloads to web applications, detecting cross-site scripting flaws for subsequent remediation.
Validates web inputs to reject script-related content that could produce XSS.
Output validation against expected content can reject or sanitize script content in generated web pages, reducing XSS exploitability.
Mitigating Controls (NIST CSF 2.0) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Secure SDLC practices directly target introduction of XSS via coding standards/testing (mostly), yet the single broad outcome leaves many specific neutralization vectors unaddressed (partial).
Patching and EOL replacement can remediate known XSS instances in libraries or frameworks (partial) but do nothing to enforce input neutralization in application code (none).
Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.
A.5.6 only promotes membership in groups to improve knowledge, receive alerts, and share information; it performs no action that stops XSS exploitation (or even the underlying neutralization defect) and is a pure dependency for other controls per the owner's labeling rule.
